70% to pass

The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0188 below. Use the white pages of The Stability Data Reference Book to determine the available GM.

A Available GM 4.1 ft
B Available GM 4.3 ft
C Available GM 4.7 ft
D Available GM 5.1 ft
AI Explanation

The correct answer is B) Available GM 4.3 ft. To determine the available GM (Metacentric Height), you need to use the white pages of The Stability Data Reference Book and the load condition provided in table ST-0188. By looking up the relevant information in the white pages, you can find the GM value that corresponds to the given load condition, which is 4.3 ft. The other options are incorrect because they do not match the GM value obtained from the reference book for the given load condition. Providing the correct GM value is essential for ensuring the vessel's stability and safe operation.
